this week's "new york times" magazine faces the changing face of the obama administration, four years after it first took office. at the time of the first inaugural, "new york times" magazine published 52 portraits of the president's top aides and advisers. i can remember reading it, looking at it. now peter is writing roughly half of the people in the photo essay are gone. some embittered by realities they did not anticipate or cast aside by a president cutting losses. the gauzy hope of 2009 has faded into the stacker realism of 2013. a washington they promised to transform is as divided as ever. peter, you know, i haven't seen the sunday times magazine, obviously, yet, but i can recall at issue, and we all recall what's encountered, what the country has encountered over the last four years. my question to you is, some of the people seem to be embittered, some of the people seem resentful of what didn't happen. are they unrealistic about what the country endured, what happened four years ago? i mean, what happened within the first three or four months of the obama administration? >>
